Vintage-Style Leather T-Straps

I bought these new from Modcloth several years ago and they've stayed beautiful and unused in my closet (in their shape-savers and dust bags) since then. They're a super cute turquoise with matching glitter on the heel and silver details at the toe and straps. Wear is very minimal--just tried on around the house. Euro size 41, it fits me at US size 10.
